Meanwhile, climate change has strong regional characteristics. In the global context of climate warming, the climate change trends and intensity is not entirely consistent. Therefore, strengthening small regional climate change research plays an extremely important role on local agricultural production, livelihood and disaster prevention. On the basis of the monthly average temperature series in Guyuan meteorological station from 1957 to 2011, the temperature trends were analyzed with Mann-Kendall test and Pettitt jump test.

Κοντά σου
ΤΟ ΠΟΙΗΜΑ κινείται στο γνωστό ποιητικό κλίμα της Πολυδούρη,
που διαμορφώνεται κυρίως από το ερωτικό συναίσθημα,
διαποτισμένο από μια γυναικεία ευαισθησία.
Κοντά σου δεν αχούν άγρια οι ανέμοι.
Κοντά σου είναι η γαλήνη και το φως.
Στου νου μας τη χρυσόβεργην ανέμη
ο ρόδινος τυλιέται στοχασμός.
Κοντά σου η σιγαλιά σα γέλιο μοιάζει
που αντιφεγγίζουν μάτια τρυφερά
κι αν κάποτε μιλάμε, αναφτεριάζει,
πλάι μας κάπου η άνεργη χαρά.
Κοντά σου η θλίψη ανθίζει σα λουλούδι
κι ανύποπτα περνά μες στη ζωή.
Κοντά σου όλα γλυκά κι όλα σα χνούδι,
σα χάδι, σα δροσούλα, σαν πνοή.
